Code Red Worm

[Philipp 6]

Just received the follow security bulletin from Microsoft:

 

The Microsoft Security Response Center, along with other organizations listed below, is jointly publishing this alert that ALL IIS ADMINISTRATORS ARE ASKED TO READ

 

A Very Real and Present Threat to the Internet:

July 31 Deadline For Action

 

Summary:

 

The Code Red Worm and mutations of the worm pose a continued and serious threat to Internet users. Immediate action is required to combat this threat. Users who have deployed software that is vulnerable to the worm (Microsoft IIS Versions 4.0 and 5.0) must install, if they have not done so already, a vital security patch.

 

How Big Is The Problem?

 

On July 19, the Code Red worm infected more than 250,000 systems in just 9 hours. The worm scans the Internet, identifies vulnerable systems, and infects these systems by installing itself. Each newly installed worm joins all the others causing the rate of scanning to grow rapidly. This uncontrolled growth in scanning directly decreases the speed of the Internet and can cause sporadic but widespread outages among all types of systems. Code Red is likely to start spreading again on July 31st, 2001 8:00 PM EDT and has mutated so that it may be even more dangerous. This spread has the potential to disrupt business and personal use of the Internet for applications such as electronic commerce, email and entertainment.

 

Who Must Act?

 

Every organization or person who has Windows NT or Windows 2000 systems AND the IIS web server software may be vulnerable. IIS is installed automatically for many applications. If you are not certain, follow the instructions attached to determine whether you are running IIS 4.0 or 5.0. If you are using Windows 95, Windows 98, or Windows Me, there is no action that you need to take in response to this alert.

 

What To Do If You Are Vulnerable?

 

a. To rid your machine of the current worm, reboot your computer.

b. To protect your system from re-infection:

Install Microsoft´s patch for the Code Red vulnerability problem:

 

Download for Windows NT 4.0

Download for Windows 2000 Professional, Server and Advanced Server

Should Win XP users download the Win 2K Pro patch?

This worm only targets a vulnerability in IIS 4.0 and 5.0. If you are running WinXP, more than likely you're running the home version, or pro version... neither of which, to my understanding, have IIS included. You only need to download and install the patches on machines running IIS.

 

This is gonna be neat.. muhaHAHAHAHAHA!!

 

Curious to see what happens.

 

Companies prolly aren't gonna have many problems... the problems are gonna be greatest with people at home who have IIS installed and don't know it, or have IIS installed but don't bother to manage it.

 

Anyways, you could always try to install the patch just in case. I'd rather err on the side of caution. Also, if you are running PWS (Personal Web Server) on Win9x, or XP if it's available (I'm no XP guru yet).. i would look into that too. Not sure if PWS has the same vulnerability.

 

Chow.

 

BTW... congrats CLUTCH!!!

WinXP Pro does have IIS - I'm not sure what version it is though (5.1 maybe?)

I don't ee a specific patch for code red. What I see is the June 18, 2001 buffer overrun patch (being applied now). Are the two the same?

Yes
